Solder paste under the microscope.

In electronics we regularly use solder paste in the assembly of printed circuit boards (PCBs). This paste comes in a variety of packages, styles, types and so on. Today I look at one small tub of solder paster under the microscope. Quite literally.

Windows ™ versus Linux on intel Galileo

Here is a really quick and dirty, non scientific comparison of a Galileo GEN1 board running Windows ™ against the same board running linux. SPI Flash version is 1.0.2. Login to windows is via telnet. Login to linux is via ssh.  Time taken from power-on to login: Linux  48 Seconds Windows 68 Seconds Time taken […]

Galileo GPIO Timing & why it doesn’t work for some.

The Intel Galileo is has Arduino UNO compatibility, yet often I see queries from someone asking why their favourite Arduino Shield won’t work, or why an interface they have made which works on other Arduino boards, doesn’t work with Galileo. Often they say Galileo is no use, or Galileo doesn’t do what it claims, or Galileo is […]

 

Dallas 1-Wire iButton teardown.

Recently I’ve been investigating 1-wire iButtons and interfacing them to different systems. I thought it might be interesting to see what’s inside an iButton. So here is my Dallas DS1990A iButton teardown.

Reading 1-Wire iButtons using Cypress PSoC 3 and 5/5LP

Previously I posted about using a standard UART to read and write to 1-Wire devices. In this post I look at how to read and write to these devices using Cypress PSoC devices.

 

Reading 1-Wire iButtons using a UART

This post takes a look at a simple 1-Wire protocol reader/writer using a standard UART for detecting and communicating with 1-Wire devices. Written in C for Linux, and running on Intel Galileo. It could easily be ported to most other platforms.

LED Matrix built and working

I’ve assembled and coded up the LED Matrix shield that I designed. It’s running on an Intel Galieo, but should also be compatible with other Arduino UNO Compatible boards. Assembly pictures and video demos are included.
